This invention relates generally to traction devices and more particularly to an improved sander for automobiles. v

One object of the invention is to provide a sander which will be operative `for depositing sand in advance of the driving wheels of amotor vehicle foy,` preventing sliding of said Wheels o a slippery surface.

Another object of the invention is to provide a sander which may be built into new vehicles or may be installed in vehicles yalready in use.

A further object of the invention is to provide a device 'of this character employing combined valve and agitating mechanism.

As still another object, the invention seeks to l provide a sander which is simple in construction.

And another object of the invention is to provide a sander which can be controlled by the driver of the vehicle by a switch on the steering wheel.

Other` objects of the invention will appear during the course of the following description.

In the drawing: i

Figure 1 is a fragmentary top plan of the chassis of a motor Vehicle and showing myimproved sander as it would appear installed on said Figure 2 is an enlarged detail sectional view,

partly in elevation, showing particularly the valve and agitating mechanism, and

Figure 3 is a side elevation of the sander ready for installation.

Referring now to the drawing, the numeral l indicates in general the chassis of a motor vehicle. The chassis l includes side members 2 .and 3, an X frame support 4 and a cross member 5, said cross member being disposed near the rear of the chassis. The chassis carries the usual wheels, the rear ones of which are shown at 6. A portion of the steering wheel is shown at 1 and the battery at 8.

In carrying my invention into eiect, I employ The body is closed Aat its upper end by aremovable top wall I3 which carries,` mediallyjof its length, the ller neck lll. 5 The iiller neck-is a body S which is formed of heavy sheet metal or other suitable material and which, as best shown in Figure 3, is substantially V-shaped in side elevation. The bodyvis rectangular in top plan and includes a ller neck H3. The body ris secured Yto the cross member 5 by bolts or other. fastening devices which extend through pairs of ears ll and l2. The pair of ears li is mounted on the upper end of the inner wall of the body while the pair of ears l2 is mounted on the inner wall near its 'lower end. As will be seen, the

. ears l2 are substantially triangular in shape.

' to the filler neck.

closed at its upper endv by'a cap lil. In this con-f nection, it should be understood that the body is so disposed that the ller'neck willbe positioned between the rear wall of the body of thevehicle and the rearvseat thereof sogthat it -will onlyrbe necessary toremove 'the rearfseatv to gain' access As best seen in Figure. 2, thefbody 'il carries,r at

`its lower end,v a dischargespout l5 whichfis formed integral with the body andisfof cylindrical shape. Associated with thefbody lisa discharge pipe I6. The discharge pipe isformed of sheet metal and has itsfuppfer end Yportion extending into the body through the discharge spoutV l5. A clamp l'l is tted about-the spout i5, which spout is slotted, if thought necessary, for rigidly holding the upper end of the pipe I6 in place. The upper end .of the pipe I6 deiines a valve seat lle, the purpose for which will be set forth'in more detail hereinafter.

The pipe i6 is relatively large in diameter throughout the upper three-fourths of its length and said relativelylarge portion terminatesv at its lower end in a discharge chamber I3, which is substantially bell shaped.V Below the discharge chamber,V the pipe I5 is restricted to form a reducedV extension or guide is. and, formed on the lower endo said guide or extension I9, is a circular attaching flange 2).Y

Riveted or otherwise suitably secured to the flange 2B, in axial relation to the pipe lQis ra cylindrical casing 2i and mounted axially within the casing is a vibrator 22, said vibrator having an armature 23 and a pole piece 2B, Y

The numeral 25 indicates the valve stem'of my device. The -valvestem 25' is slidably mounted in the Vguide i9 and extendsthroughout the -length of the discharge pipe and downwardly into the casing 2| where it is connected with. the `armature 23. The upper end of the stem 25 carries a ball valve B which is engageable with the valve-seat Ila. In this connection, it should be understood that, if desired,- valves of other shapes may be employed in lieu of the ball valve 26. Mounted on the ball valve," axially thereof and extendingupwardly into the body 9, is a supporting stem21 and mounted on the upper end of the supporting stem is a substantially conical agitator 28. As will be pointed out in more detail hereinafter, the agitator alsoV serves as a deector. Y

In order'to lead sand to Apoints from which it may drop to the surface of the ground in front of the wheels 6, I provide discharge `tubes 29 which have their corresponding inner ends connected with the Vdischarge chamber I8. The tubes 29 Vcan be made of soft copper or other suitable Vmaterial and are of a suiicient'diameter to allow free sand flow. Y

YThe vibrator is to be energized by current from Y the battery 8. To permit ease of control of my sander, I employ a switch 38 which is mounted on the steering post which supports the steering wheel 1. The switch may be ofthe push button type and has one terminal connected with o the battery Sby a conductor 3l.

minal of the switch is connected with one terminal of the vibrator by a conductor 32. The otherA 'Ihe other tergized; When'this is done, the valve stem 25 will f be intermittently shifted upwardly for intermittently unseating the valve 26. Sand will thus be permitted to flow, internnttently,V through the discharge pipe I6 and Vthrough the tubes 29 to points where it may fall on the slippery surface ahead of the Wheels E. The sand will, of course, improve traction. n

When the stem `25 is shifted, the agitator 28 Awill also be shifted for keeping the sand in a flowing Vcondition in the body. It isV desired to point out, also, that the agitator will act as a defiector and will deflect flow of sand from above the valve so that free movement of the valve will be assured. v V-'It is recognized that the stem 25 will be required to lift against the weight of the sand in the body. However, in View of the fact that the agitator is conical in shape and the'fact that the stem travels but a short distance, it is thought that movement of the stem will not be arrested by the weight of the sand. p j

My improved sander is of simple construction and maybe easily installed on vehicles already in use or installed on them during manufacture.

Having thus described the invention, What is claimedv as new is:

AY sander including a body having a discharge spout, a discharge pipe having its upper end provided with a valve seat'and its intermediate portion enlarged laterally to form a circumferential chamber, means securing the upper end of the discharge pipe in the-spout, said pipe having its lower end reduced in diameter to form a guide having'a' lateral attaching flange at its lower end, a casing secured to the ange, a valve stem shiftable in the discharge pipe, a valve on the valve stem and engageable with said seat, a vibrator in Vthe casing and connectedwith the Valve stem, said vibratorbeing energizable for shifting the stem and valve for allowing sand flowr from the body, and pipes communicating with said chamber for leading sand to surfaces in advance of vehicle wheels for aiding traction thereof. v WALTER R.
